Definitions
- the invention relates to a mounting bracket for use in telecommunication arrangements and, in particular, a mounting bracket to hold a modular cross-connect unit.
- a telephone station set or a computer terminal may be connected to illustratively a key telephone system or a local area network, respectively, via a so-called cross-connect arrangement.
- Such cross-connect arrangements are usually located in a wiring closet where they are fastened to a wall.
- such arrangements have been modularized and employ the so-called universal telephone jack and plug to allow users to make their own connections without using skilled personnel.
- electronic circuitry has been added to cross-connect arrangements for local area networks to allow the user to either expand the network or change its configuration.
- prior cross-connect arrangements are fastened directly to a wall it is very difficult and burdensome to replace a malfunctioning universal telephone jack.
- the cross-connect unit is mounted in a bracket which allows the unit to be easily removed therefrom.
- the bracket in accordance with the invention, is formed from a length of wire in a double-L configuration such the vertical legs of the bracket are spatially separated by a U-shaped section that is offset toward the horizontal legs. Another length of wire bridges and attaches to the horizontal legs. Grooves formed in the cross-connect unit engage the U-shaped section and bridging wire, respectively, which firmly press against the unit as a result of the flexibility of the bracket's L shape.
- the bracket rather than the cross-connect unit itself, is fastened to a wall by passing fastening devices through holes formed in the vertical legs and into the wall of the wiring closet.
- the ends of the horizontal legs are bent such that they slant downward so that the crossconnect unit can be easily inserted in the bracket.
- the end of one of the horizontal legs is bent a second time to form a U-shaped section for holding illustratively a label holder bearing a label identifying the unit mounted in the bracket.
- FIG. 1 depicts a mounting bracket formed in accordance with the invention
- FIG. 2 depicts a front perspective view of a modular crossconnect unit adapted to be mounted in the bracket of FIG. 1;
- FIG. 3 depicts a rear perspective view of the unit of FIG. 2 mounted in the bracket of FIG. 1.
- mounting bracket 10 is formed, in accordance with the invention, from a length of wire into a double-L configuration. Another length of wire 15 bridges the horizontal legs 16 and 17 at substantially the midpoint thereof.
- the wire that is used to form the double-L portion of bracket 10 is illustratively 0.1560 inch nickel plated steel wire and wire 15 is illustratively 0.120 inch nickel plated steel wire.
- the length of wire 15 as measured from point i to point j is illustratively 2.4 inches, which is slightly longer than the width w of the spatial separation between horizontal legs 2 or members, 16 and 17.
- Wire 15 is attached to legs 16 and 17 using, for example, the well-known resistance welding technique.
- wire 15 serves as a retaining clip, which engages a corresponding groove formed in a housing for a modular cross-connect unit. It also serves to maintan the spatial separation between legs 16 and 17.
- the length of horizontal legs 16 and 17 as measured from point e to point f is illustratively 5.8 inches. (Hereinafter wire 15 will be referred to as retaining clip 15).
- end portions 18 and 19 of horizontal legs 16 and 17, respectively are offset, or slanted, in the downward direction, illustratively 45 degrees, from the plane defined by legs 16 and 17.
- the space M between the overlapped sections is used to pass the cables through, thereby providing a means to neatly route a large number of cables (shown in FIG. 2).
- End portions 18 and 19 are bent inward at point g and h, respectively, and overlap each other, as shown.
- End portion 18, being longer than end portion 19 is further bent to form a U-shaped section indicated at 28.
- a label holder bearing a label may be clipped onto U-shaped section 28 to identify the cross-connect unit that is mounted in bracket 10. Ends 18 and 19 could, alternatively, be tack-welded together.
- bracket 10 The spatial separation between vertical legs 2 or members, 20 and 21 of bracket 10 is maintained by the width of section 22, which bridges legs 20 and 21.
- the width of member 22 is illustratively 2.2 inches as measured between points c and d.
- Section 22 and respective portions 23a and 23b of veritical legs 20 and 21 form a U-shaped section which slants forward, illustratively 45 degrees, from the plane defined by vertical legs 20 and 21.
- This U-shaped section serves as a retaining clip and slips into a corresponding groove that is formed in the cross-connect unit, as will be shown below.
- the height of bracket 10 as measured vertically between points c and e is illustratively 10.4 inches. (The U-shaped section formed by section 22 and portions 23a and 25b will hereinafter be referred to as retaining clip 22).
- Bracket 10 may be fastened to illustratively a wall by pasing an appropriate fastening device through holes 25 and 27, respectively, and into the wall.
- Holes 25 and 27 are formed in vertical legs 20 and 21, respectively, using, for example, the well-known swaging and piercing process. Swaging reduces the thickness of the steel wire at the point where the holes is to be formed such that the steel wire spreads out, as depicted at 24 and 26. The center of the swaged material is then pierced to form a hole, such as holes 25 and 27.
- FIG. 2 there is shown a front perspective view of the housing that is about to be inserted into bracket 10.
- housing 30 may be used, for example, to house a modular cross-connect unit.
- housing 30 will be referred to as unit 30.
- unit 30 includes two columns of universal telephone jacks, such as jack 41, which are mounted and accessed at the front 44 of unit 30.
- a user may establish a connection between, for example, a computer terminal and a local area network, using a patching cable, such as one of cables 42 or 43, that is terminated at both ends with a universal telephone plug.
- the user establishes such a connection by merely plugging one end of the cable into one jack on unit 30 to establish a connection to the network and plugging the other end of the cable into another jack that may be mounted on a computer terminal or on another unit 30 to extend the connection of the local area network.
- unit 30 commences with engaging groove 31 with retaining clip 22.
- Unit 30 is then rotated downward and into bracket 10. Since the height of unit 30 is illustratively larger than the height of bracket 10, i.e., the latter being measured from the retaining clip 22 to the top of clip 15, unit 30 will cause the clip 22 to flex upward and cantilevered horizontal legs 16 and 17 of bracket 10 to flex downward to allow groove 33 to be positioned over clip 15.
- the spring function of the double-L configuration allows clip 22 and legs 16 and 17 to relax, thereby allowing clip 15 to slip into groove 33. Insertion is facilitated by the fact that end portions 18 and 19 of horizontal legs 16 and 17 are slanted downward, as mentioned above.
- FIG. 2 also shows label holder 40 clipped onto the aforementioned U-shaped section 28 of horizontal leg 16.
- FIG. 3 there is shown a rear perspective view of unit 30 inserted in bracket 10.
- the shape and contour of groove 31 formed between the top 38 and rear 39 surfaces of unit 30 matches the shape and contour of retaining clip 22 of bracket 10, such tht clip 22 slips into groove 31 as unit 30 is being inserted into bracket 10.
- Retaining clip 22 is held in groove 31 by the wall 32 of groove 31.
- the width of wall 32 i.e., the distance between the end points k and l thereof, is illustratively 2.09 inches.
- unit 30 includes an alignment bar, or key, 34 that is illustratively molded into the rear 39 of unit 30 near its bottom to align unit 30 with bracket 10.
- Alignment bar 34 is disposed between vertical legs 20 and 21 when unit 30 is in alignment with bracket 10, thereby allowing groove 33 to engage retaining clip 15. If unit 30 is not in alignment with bracket 10, then bar 34 makes contact with either leg 20 or leg 21 and prevents retaining clip 15 from slipping into groove 33.
- Unit 30 also includes slots 35 and 36. Slots 35 and 36 are adapted to cover the heads of fastening devices that may be inserted into holes 25 and 27, respectively, so that the heads do not interfere with the insertion of unit 30 into bracket 10.
